Blistering on outside & inside after week of use.

I purchased with great enthusiasm, but after a week of use, I've had to discontinue. My upper lip broke out in blisters on the outside and inside. The lip is swollen even after discontinuing for one week. My lips felt very dry and stiff as well, even though I applied the gloss several times a day. I read other reviews with similar or more severe reactions. One review listed ingredients used in the product...scary. The product did stay on, but after reading about the ingredients, I am highly concerned about the safety.
